Popis: Background: Viscum album (VA) preparations consist of aqueous extracts of different types of lectins of VA. Mistletoe lectins have both cytotoxic and immunomodulatory properties that support their study for the development for cancer therapy. However, the mechanisms of the antitumoral properties in vivo of mistletoe lectins are not fully understood. Because endothelial cells (EC) play a pivotal role in tumor angiogenesis, we tested the hypothesis that VA extracts induce endothelial cell death and apoptosis. Material and Methods: We investigated the effect of various VA preparations on both human venous endothelial cell (HUVEC) and immortalized human venous endothelial cell line (IVEC) using morphologic assessment of EC, FACScan analysis after propidium iodine and annexin V
